Cleared and rescheduled tasks come back to old date/time slots

I just moved my ACT 11 to a new machine running Windows 7 Professional. After a few days of running OK, I now have two bizarre issues:1. I can't get the DB on the new machine to sync with the remote DB on my laptop which is running Windows 7 Home. It sync'ed fine for about a week.2. Tasks (meetings, calls, to do's) that have been cleared or rescheduled to a future date reappear in the date/ time slot they were moved from and some to do's reappear as meetings. This one makes Act unusable for me.

Re: Cleared and rescheduled tasks come back to old date/time slots

1. No message when I sync with remote DB. It all goes through but, when complete, the tasks/calls/meetings on the remote DB are not the same as on the main DB.

2. I sync with Outlook, one direction only: ACT to Outlook.

3. I sync with ActConnect, one direction only: ACT to ActConnect.

Yesterday, I restored an older version of the DB, erased or cleared what needed to be erased or cleared, and moved tasks/calls/meetings to future date where appropriate. Basically, I got the DB back to usable condition. I immediately created a backup copy and started working. At one point, I cleared a task and some, not all, of the old tasks/calls/meetings came back to repopulate the calendar. I restored the 10-minute old backup and kept working. At this point, I'm backing up every 5 minutes or so and having to restore every so often.
